AHK, I saw your posts from a few pages back:
Stress does not excuse the fact that she lashed out at Salad, the same exact way Sasuke lashed out at Sakura time and time again. I don't excuse Sasuke for that shit, and I damn sure won't excuse Sakura, who i once held to much higher standards than Sasuke could even dream. There is no excuse for it. Look at the damage she caused! One foot closer and Salad is dead! It's revolting that I even have to stick up for that child, she shouldn't exist, but still, I won't hold back when i criticized Sasuke for the same thing. She damn near could have ended a child's life, and she did it out of the need to intimidate her into silence.
So, the thing about Sakura and punching the ground.... I don't see it as an example of child abuse. Just a weak connection from Sakura to Tsunade. Since Tsunade's been shown to behave like this to Sakura many times, and slapping and physical comedy is big in this manga, I think this is one of those overblown reactions. Not abuse, because when Tsunade reacted that way to Sakura, it wasn't considered abuse either. (In real life, that's unacceptable. But this is a manga, and a terrible one at that.)
But here's the problem with the scene: Where Tsunade does punches the ground and destroys whole swaths of land, people step back and look at her with awe and put her in a place of power. But if Sakura does it, she is shown destroying her own home and passing out. She is punished for her power, and only ends up hurting herself.
So Kishimoto just continues to undermine Sakura. He is constantly punishing her for speaking out, using her abilities, having a temper, etc. This is why he's sexist. Because where Naruto rewarded for the same personality, skills and strength, Sakura is put down and her self-empowerment is punished.
There has yet to be a positive outcome for Sakura in the ending. Not one single thing has happened good for her.
And I think the reason is because she's not Hinata. She's not passive and flawless and created to be easy-to-look-at and undemanding. Sakura is like a real life girl, and Kishimoto doesn't know how to write for those.
I'm sorry to say, but I don't expect much more for Sarada. He's never written well for females. I'm not holding out any hope that he's changed now.
I understand that you're talking about the emotional core of what's happening.... And it's true. In real life, reacting that way would be reprehensible. But I just don't think Kishimoto thinks that deeply. Sakura is just a disposable character now. She's a one-time main character who has now become the butt of some sexist joke for Kishimoto. He just keeps going back to it, but nobody with a brain thinks it's funny.
